Notes:
The semipermanent charge distribution at saturation in a germanium-doped silica planar waveguide is modeled for the case of seeding by a low-intensity fundamental wave and its second harmonic both propagating in the lowest order transverse magnetic mode. Based on the asymmetric photoionization model, the total current in the waveguide is taken to be the sum of the photoinduced current and the current due to the resulting static electric field caused by the charge separation. This current is used in the charge conservation equation to determine the charge distribution at saturation which is then used to compute the resulting static electric field inside and outside the waveguide. To compare with other models, the spatial profile of the resulting static electric field is compared to the direct current (dc) optical field due to a four-wave mixing process. © 1995 American Institute of Physics.
